What’s the Cost of Pressure

Specific grille, diffuser, or terminal unit minimum pressure requirements are often overlooked during design but with so many units on a projects, they can greatly affect operating costs. Individually pressure differences between two models of grilles, diffusers, or terminal units may be small but there may be thousands of units on a project. The cost can add up over the life of a building.

With the drive toward reducing energy usage in buildings, annual operating costs are becoming more important that ever before. The Cost of Pressure tool above can calculate the difference in operating cost of any two units based on the difference in their minimum pressure requirements.
